Build Your Own Big Brake Kit.

These rotor hats provide one of the most difficult to source pieces that required to attach off-the-shelf 11 inch diameter rotors, to a 1990-1993 Isuzu car.

In order to build your big brake kit, you will need to obtain these other needed parts which are not included ($~1336):

• PN 28.440.3103 and 28.440.3104 Stoptech brand 280mm x 20.6mm rotor rings ($132).
• Two PN 89.000.0002 Stoptech AeroHat mounting hardware kits (drive pins / bobbins) ($76).
• Isuzuperformance Brake Caliper Brackets ($430).
• Wilwood Dynapro Radial Mount Brake Calipers ($406).
• Wilwood BP-10 Brake Pads 150-8850K ($42), or any Wilwood 78XX pattern brake pad.
• Isuzuperformance Brake Line/Hose Set for Wilwood Calipers ($250).

Question:

Why not use the less expensive Dynalite calipers?

Answer:

• The Dynalite calipers are not available in 1.5 inch diameter piston size, which is the minimum size appropriate for use on the 90-93 Isuzu cars.
• The Dynalite caliper lower pad guides, cast into the caliper body, will not clear the bobbins of the Stoptech rotor.
• The Dynalite caliper will not clear the spindle mounting tabs of the 90-93 Isuzu cars.

Question:

Why do we use a 11 inch brake rotor?

Answer:

• To allow for the use of 15 inch wheels and 195/50-15 or 205/50-15 racing tires. Commonly available 12 inch rotors with brake calipers installed will not fit within a 15 inch wheel, and would require the use of 16 inch or larger diameter wheels, with lower profile tires, which are less commonly available in racing tires, much more expensive, and less forgiving for driver technique (less desirable).

The Story Behind This Item

When the 90-93 Isuzu cars were introduced, they were among the top performers in braking performance in the category of sporty small cars. But braking technology dramatically improved in the 25+ years that followed. New small cars that are currently on the market have much more powerful braking systems, with shorter stopping distances. Upgrading the brake system of a 1990-93 Isuzu car improves both safety and enjoyment of these cars, bringing them up to, and surpassing the current standards for braking performance.

We have been using 11 inch front big brakes on our race and street vehicles for almost ten years now.

We are making these parts available for purchase so that owners of these vehicles can assemble a true racing quality, professionally designed, brake setup.

We are offering these parts in order to allow the customer the option of customizing their brake system to match their needs and desires. The calipers are available in different sizes providing different clamping forces. The calipers are available in multiple standard and customized colors. In addition, obtaining the off-the-shelf parts from the vendors with the lowest prices, the customer can assemble their brake setup for the lowest cost possible.

Includes

• 2 - Brake Rotor Hats (One Left and One Right) for use with Stoptech 280mm x 21.6mm brake rotor rings PN 28.440.3103 and 28.440.3104.
  • Brake rotor hat is made of 6061-T6 aluminum, hard anodized, and dyed black.
    
  • The hat is designed to use Stoptech bobbins, so that the rotor is floating. This prevents the fasteners from loosening when the rotor heats and cools.
    
  • Hat design provides ducts for air flow between the bobbin mounting points, between the hat and the rotor, for additional cooling.

Installation

• Attach Stoptech rotor rings to Isuzuperformance aluminum brake rotor hats using the Stoptech bobbins, per Stoptech's torque instructions.
• Place two piece rotor assembly onto hub. Apply a thin coat of anti-seize between mounting surfaces if desired.
• Attach caliper bracket to spindle, per factory shop manual instructions.
• Attach brake calipers to brake caliper brackets, per Wilwood's instructions.
• Attach brake hoses and bleed brakes, per Wilwood instructions.
• Enjoy driving your vehicle with new brake rotors attached.
